Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504076, here are decompositions:

103 + 31503973 = 31504076
193 + 31503883 = 31504076
223 + 31503853 = 31504076
229 + 31503847 = 31504076
277 + 31503799 = 31504076
349 + 31503727 = 31504076
433 + 31503643 = 31504076
523 + 31503553 = 31504076

Showing the first eight; more decompositions exist.
